18 Claims.

This invention relates to machines for operating on shoes and is illustrated as embodied in a machine for preparing a welted shoe for the sole laying operation by trimming off or butting the ends of the welt and tacking the overlasted margin of the upper adjacent to the ends of the welt to the insole. Such a machine is illustrated, for example, in United States Letters Patent No. 1,709,347, granted April 16, 1929, upon an application of George Goddu et al. An improved machine of this type is illustrated in my copending application Serial No. 174,542, filed November 15, 1937. The machine illustrated in my copending application is provided with operating instrumentalities common to machines of this type comprising devices for supporting both end portions of a welt during the butting operation, welt butting knives, shear members or anvils against which the knives operate to butt the welt, and fastening inserting means for securing the upper in the region of the welt butts to the insole. Said machine is also provided with means for pounding and flattening the inseam substance in the region of the welt butts, and means for supporting the shoe during the pounding operation. The knives move lengthwise of the shoe to butt the welt ends which are supported on the crease finders at an inclination such that the knives make a long tapering cut through the end portions of the welt.

In operating on shoes provided with storm welts, machines of this type are required towork the butted end portions of the storm welt inwardly over the insole. The storm welt usually employed has a central longitudinal rib projecting upwardly from its upper-attaching surface and serving to close the welt crease. After butting this type of a welt the butted or skived off portion of the rib extends from the butted end of the welt in the form of a tapering tab. In

order to give the shoe a finished appearance this tab must be worked in over the insole into a position in which it will be inconspicuous in the completed shoe. Machines of the type referred to have been provided with means for working the tab at the butted end of a storm welt inwardly over the insole, mechanism for this purpose being shown inUnited States Letters Patent No. 1,614,836, granted January 18, 1927, upon an application of George Goddu.

It is an object of the present invention to provide an improved means for working the tab at the butted end of a storm welt inwardly over the insole and with this object in view a feature of the invention consists in the provision, in a welt butting machine, of a member, herein illustrated as a welt bender, for working a butted end portion of the welt of a welted shoe, such for example asthe tab on the butted end of a storm welt, inwardly toward the middle of the shoe bottom, 2, crease finder for supporting the welt for the butting operation, and a carrier in which both the crease finder and the welt bender are mounted for operative movement relatively to the carrier and relatively to each other widthwise of the shoe. In the illustrated machine such movement of the crease finder serves to retract it prior to the inseam pounding operation in order to obviate the formation of an impression of the crease finder in the welt by the pounding of the inseam substance. As herein illustrated, the crease finder is advanced and retracted by the same actuator which operates the Welt bender for working in the tab of the'storm welt, the crease without performing its intended operation. In

accordance with a feature of the invention the illustrated machine is provided with means for holding the welt end against movement away from the shoe bottom during the operation of the welt bender and thereafter until the welt end is secured to the shoe bottom. As herein illustrated, the welt .end is held against movement away from the shoe bottom by the nozzle through which fastenings are driven to secure the welt end to the shoe bottom. To this end the nozzle is brought into a position adjacent to the topof the welt end prior to the operation of the welt bender.

It is the usual practice in butting welts on welt.

butting machines of the illustrated type, to position the shoe lengthwise thereof by bringing the in order that the welt butting knives in the course of their movement toward the toe end of the shoe will not strike the shank portion of the shoe bottom. It will be understood that in changing the position of the shoe relatively to the knives the relation of the shoe to the fastening inserting means is correspondingly altered. It is an object of the present invention to provide a machine organization which permits an adjustment of the fastening inserting means similar to said adjustment of the anvils whereby the fastenings may be located in any desired position lengthwise of the shoe regardless of the position of the anvils.

With the above object in View, a feature of the invention consists in the provision in a welt butting machine having welt butting anvils which are adjustable lengthwise of the shoe, of fastening inserting means for securing those portions of the shoe upper margin in the regions of the welt butts to the shoe bottom, and means for adjusting the fastening inserting means lengthwise of the shoe.

In the illustrated machine the shoe is located heightwise thereof relatively to the operating in strumentalitiesby moving the shoe upwardly into engagement with a holddown member, such upward movement being effected by elevating the shoe supporting member. It has been found desirable that the holddown member be located away from its operative position when the machine is at rest and remote from the path of movement of the shoe as it is introduced into the machine in order to facilitate the positioning of the shoe. Accordingly, the illustrated machine is provided with means for automatically moving the holddown into a remote position to facilitate the introduction of a shoe into the machine. As herein illustrated, the holddown is moved into its remote position by the operation of a toggle which, in its straightened position, holds the holddown against upward movement.

Other features of the invention relate to novel means for retracting the welt butting anvils into positions remote from the shoe bottom in order to provide clearance on the shoe bottom for the operation of the fastening inserting means, and novel fastening receiving nozales constructed and arranged to facilitate removal of fastenings which have become fouled therein.

These and other features of the invention will now be described with reference to the accompanying drawings and will be pointed out in the appended claims.

Fig. 13 is a plan view illustrating the rear portion of a shoe in the machine after the operations performed thereon by the illustrated machine have been completed.

The illustrated machine is provided with operating instrumentalities common to machines of this type comprising crease finders which support the end portions of the welt for the butting operation, welt butting knives which move lengthwise of the shoe toward its heel end making a long tapering cut totrim off the waste ends of the welt, and shear members or anvils which cooperate with the knives to complete the butting of the welt by a shearing action which produces a substantially square welt end. For securing the overlasted margin of the upper in the region of the butted ends of the welt to the insole, the illustrated machine is" provided with tack driving mechanism which is similar in its construction and operation to the tack driving mechanism of the machine illustrated in my copending application above referred to. The illustrated tack driving mechanism drives one tack at each side of the shoe in a location selected by the operator and exerts a pounding action against the inseam substance in the region of the butted ends of the welt in order to flatten the end portions of the inseam rib against the insole.

Referring now to Fig. 1, the shoe is held against downward movement during the pounding operation by a jack or spindle 20 which is moved upwardly against the cone of the last before the pounding operation takes place. For cooperating .With the jack 20 to hold the shoe in position for the pounding operation, a holddown is constructed and arranged to engage the shank portion of the shoe bottom. The jack urges the shoe upwardly against the holddown, the holddown serving to locate the shoe heightwise thereof. As illustrated in Fig. 1, the holddown. comprises a sliding rod 22 mounted in forward extensions 24 of the machine head and a shoe-engaging foot 26 secured to the lower end of the rod 22 and arranged to engage the heel seat portion of the shoe bottom. Secured to a bracket 28 on the rod 22 is a shank-engaging foot 30 which is positioned heightwise of the shoe by adjusting nuts 32 on a threadedstem 34 extending upwardly fromthe foot 38. The shank-engaging foot 30 is spaced from the heel seat engaging foot 26 by a link 36. The holddown is moved vertically toward and from its operating position by the operation of a toggle comprising links 38 and 40 which connect the upper end of the slide rod 22 to a fixed bracket 42. When the machine is at rest the holddown is elevated as shown in Fig. 1 in order to facilitate the introduction of the shoe into the machine. At an early stage in the operation of the machine the toggleis straightened to move the holddown downwardly into its operating position by the upward movement of a cam lever 44' which is fulcrumed at 46 and. is operated by a cam on the cam shaft 48. At its forward end the cam lever 44 is provided with a head 58 having a cam face which during the upward .m'ovement of the head operates a lever 52 to straighten the toggle, said lever being fulcrumed at 54 and. connected to the upper toggle link 38 by alink 56. After the operations upon the shoe have been completed, the cam lever 44 returns to its initial position, illustrated in Fig. 1, and. a spring pressed plunger 58 moves the lever 52 to the left as seen in Fig. 1, thus bending the toggle and lifting the holddown to its rest position.

In operating on shoes provided with storm welts, the illustrated machine is provided with two welt benders or fingers one of which is illustrated at 68 (Fig. 3) constructed and arranged to operate on the butted end of the welt to work it inwardly toward the center of the shoe bottom. The butting of a storm welt, such as the welt 64 in Fig. 3, forms a tab 62 at each end of the welt. The tab 62 is an extension of the rib of the storm welt which rib extends downwardly from the body portion of the welt. It will be seen that the finger 68 engages the tab 62 and also that portion of the welt rib adjacent to the tab. The finger 68 is moved to the right, as seen in Fig. 3,. after the welt has been butted to bend the butted end inwardly toward the center of the shoe bottom and the finger holds the weltbutt in this position during the tacking operation. Preferably, the tack driver is so adjusted that the tack is driven through the tab 62 to hold the welt butt in the position in which the finger 68 locates it. The Welt engaging finger 68 is removably secured to a slide 66 (Fig. 12) which is mounted in a head 68 (Figs. 1, 2 and 12) for movement widthwise of the shoe. As illustrated in-Fig. 1, the head 68 is mounted on a bracket 18 which is fulcrumed at 12 for swinging movement toward and from the shoe. It will be understood that another head like the head 68, having a welt engaging finger corresponding to the finger 68 is provided at the right side of the machine. For simultaneously operating the welt engaging fingers, the illustrated machine is provided with a lever I4 (Fig. 1) secured to a rockshaft I6 and operated by a cam on the cam shaft 48. At each end of the rockshaft I6 there is secured a short arm having a beveled gear segment formed therein. The short arm at the left of the machine is illustrated at 18 in Fig. 1 together with the train of mechanism through which said arm operates the slide 66. It will be understood that a corresponding arm and train of mechanism are provided at the opposite side of the machine for operating the slide at the right of the shoe. The gear segment at the end of the short arm I8 :meshes with a beveled gear 88 at the rear end of a rockshaft 82. The rockshaft 82 has a universal connection to a sleeve 84 which is fiuted for the reception of a shaft 86 the rear portion of which is provided with longitudinal teeth 88 which slide in the flutings in the sleeve 84 and 'provide a connection whereby the rotation of the sleeve is imparted to the shaft. It will be understood that this construction permits adjustment of the head 68 in the direction of the length of the shaft 86. At its forward end the shaft 86 has a universalconnection to a rockshaft 98- mounted in bearings in the bracket I8. Secured to the rockshaft 98 is an arm 92 (Figs. 1 and 2) which carries at its upper end av shortshaft 93 having at its forward end a roll 94 which is:pos itioned in a square cut notch 96 in the slide 66. The butted end of the storm welt 64 isrelatively thin and the operation of the finger 68 tends to cause the finger to lift the welt end and pass under it without bending it inwardly. To counteract this tendency the welt end is held against upward movement by a tack nozzle I'H (Fig. 9) which is moved downwardly prior to' the operation of the finger 68 into a position in which it holds the welt end against upward movement but does not press against it or in any way interfere with the bending of the welt end inwardly toward the center of the shoe bottom by the operation of the finger 60.

Also mounted in the head 68 is a slide 95 (Fig. 2) which carries a welt butting anvil 91 and a slide 98 which carries a crease finder I08. During the welt butting operation, the crease finder is positioned in the welt crease as illustrated in Figs. 3 and 12. After the welt has been butted and before the pounding operation occurs, the crease finder is withdrawn from the welt crease in order that no imprint thereof will be formed in the Welt in the pounding operation. For advancing the crease finder into the welt crease and withdrawing it therefrom the crease finder slide 98 is provided with a connection to the slide 66 comprising a ball I82 which is mounted in a hole provided in the slide 98 and is arranged to enter a socket I84 in the slide 86. In the operation of the machine the welt engaging finger 68 operates after the crease finder has come to the limit of its advancement and the illustrated construction is such that the ball I82 is removed from the socket in the slide 66 when the crease finder comes to the end of its advancement in order to permit further advancement of the slide 66 independently of the crease finder slide 98. During its operative movement, the finger 68 moves from its position in Fig. 2 into its position inIFig. 3 bending the welt end inwardly into the position in which it is shown in Fig. 3. While the finger is in this position the tacker (hereinafter described) is pressed against the welt end to hold it in the position into which it is brought by the finger whereupon the finger is withdrawn into its position in Fig. 4. During the withdrawal of fromits position in Fig. 2 to its position in Fig.

4. The ball I82 serves to lock the slide 66 to the crease finder slide 98 during the remaining portion of the retracting movement of the finger 68 and also during part of the advancement of the finger from its position in Fig. 4 into its rest position in Fig. 2 which occurs between the tacking operation and the end of the machine cycle. During the advancement of the slide 66 a stop I I8 at the outer end of the crease finder slide 98 engages the head 68 (Fig. 2) and prevents further advancement of said slide. As the slide 66 continues to advance, the ball I82 is cammed forwardly by the outer wall of the socket I84 in the slide 66 and seated in a socket I88 in the head. In this position the ball is confined by the slide 66 as said slide continues and completes its operative movement. In this position the ball I82 locks the crease finder slide 98 with the crease finder in its advanced position and the slide 98 his remains thus locked until the slide 66 is again retracted.

For retracting the welt butting anvils in order to permit tacks to be driven through those portions of the over-lasted margin of the upper which are covered by the anvils during the welt butting operation, the illustrated machine is provided with a cam lever II6 (Fig. fulcrumed at II8 to the machine head and operated by a cam on the shaft 48. The lever II6 operates a slide I28 (Fig. 6) provided at its forward portion with a transverse groove I22 (Fig. '7) in which are mounted blocks I24 swiveled on the heads of screws I26 carried by inward extensions of slides I28 mounted in guideways in swinging brackets I48. The anvils 91 are retracted by novel mechanism operated by the slides I28 comprising levers I32 (Fig. 6) which are fulcrumed at I34 on the brackets I8 and are provided at their forward ends with rolls I36 which operate in slots I38 in the slides 95 which carry the anvils. Projecting outwardly from the slides I28 are arms I42 which carry at their outer ends rolls I44 which, as illustrated in Fig. 6, operate in cam grooves I46 in the anvil retracting levers I82. As in the machine illustrated in my copending application the slides I28 carry welt butting knives MT. The knives are operated during the first part of the operative movement of the slides I28 which is a movement to the right as seen in Fig. 6. During the welt butting operation the rolls I44 move idly through the forward portions of the grooves I46 and after the welt has been butted said rolls operate in the outwardly extending portions of said grooves thus operating the levers I32 to retract the .anvils.

The illustrated tack driving mechanism is in most respects similar in its construction and operation to the tack driving mechanism illustrated and described in my copending application above referred to. Referring to 8. the tack driving mechanism at the left of the machine is mounted on the bracket I 48 which swings on a vertical shaft I50 in the machine head and is provided with a guideway I52 which, as illustrated in Fig. 9, extends diagonally downward and toward the center of the machine. Mounted in the guideway I52 is a slide i 8 having a long hub I56 (Fig. 8) on which is slidably mounted a sleeve I58 to which is secured a front plate I60. Two horizontal keys I62 are secured to the front plate I68 and are mounted in grooves I64 in a slide I66 which is confined between the front plate I69 and flanges I58 which extend outwardly from the rear portion of the sleeve I58. The slide I66 has a round opening I61 through. which extends the sleeve I58 and this opening is large enough to permit horizontal adjustment of the slide. The slide I66 carries a sliding member I18 in which is incorporated a tack receiving nozzle I'II (Fig. 9). For adjusting the slide I96 genera ly widthwise of the shoe. a hand screw I'M (Fig. 8) is threaded into a tapped hole in the head of a pin H6 in the slide I66 and is journaled in a bearing in a bracket Ila extending outwardly and upwardly from the front plate I69. The screw I I4 is held against endwise movement in the bracket by a collar I88 and a shouldered portion I82 of said screw. For adjusting the slide I86 generally lengthwise of the shoe a hand screw I84 is threaded into a tapped hole in the center of the hub I56 of the slide I54 and is held against longitudinal movement relative to the front plate I68 by acollar I86 and the shouldered forward portion 88 of the hand screw. It will be seen that in adjusting the tacker widthwise of the shoe the slide I66 moves in a path extending at right angles to the hand screw I84 between the front plate I68 and the flanges I68 of the sleeve I58, while in the adjustment of the tacker lengthwise of the shoe the sleeve !56 together with the front plate I68 and the slide I66 move as a unit longitudinally of the hub I56 of the slide I54. For holding the tacker assembly against turning movement about the hub I56, the sleeve I58 has an upward extension I98 (Fig. 9) which is slidably mounted between the inner walls of forward extensions I92 of the slide I54. For operating the tack driving pin I72 the illustrated machine is provided with mechanism similar to that disclosed in my copending application comprising a compression spring I94 mounted in a barrel I96 on the slide I66. The spring imparts upward pressure to the outer end of a lever I98 fulcrumed at 260 on the slide I 66. The lever I98 operates a slide 282 which is carried by the member I18 and has mounted in its lower portion the tack driving pin. I12. The spring i9 1 operates in the course of the downward movement of the slide I58 upon the withdrawal of a latch member 284 which engages the outer end of the lever I98. The latch member is fulcrumed at 265-on the slide I 66 and has an angular extension 268 which, in the course of the downward movement of the tacker assembly, engages a tripping pin 2H] on the bracket hi8 and causes the latch member 284 to be disengaged from the lever I98. The slide I54 is moved downwardly by the operation of the cam lever 44 (Fig. 1) which operates the holddown. The lever 44 operates a slide 2I2 (Fig.9) on the shaft I59 which in turn operates a lever 2M fulcrumed at 2 IE on the bracket I58 and connected by a link 2 I8 to the slide I54.

The illustrated machine is provided with tack nozzles one of which is illustrated in Fig. 10. Said nozzle comprises a pair of headed plugs 228 which are mounted in a cross bore 222 in the lower end portion of the member I 18 and meet at the center of said bore. The inner end face of each of the plugs 228 has a recess 224 providing half of a tack receiving pocket into which tacks are delivered through a tube 226 (Fig. 9). For holding said tack pocket in tack receiving position each plug 229 has a longitudinal groove 228 into which projects the end of a pin (not shown) mounted in the member H8. The plugs 226 are positioned longitudinally of the bore 222 by two leaf springs 232 which hold the inner end faces of the plugs against each other under light pressure. The lower portion of each spring 232 has a V-shaped offset 234 which is seated in an end groove in one of the plugs 228 and at its upper end each of the springs has a similar V- shaped offset 236 which is seated in a suitable recess in the member I79 thus holding the spring against movement longitudinally of said member. Each spring 232 is held in position by a T-shaped pin 238 (Fig. 11) which is pinned in a socket in the member I18 and extends through a slot 24!] in the spring and is secured to said member. Whenever a tack becomes fouled in the tack pocket it may readily be extricated by a small screw driver or similar tool after first removing one of the plugs 228. The illustrated construction permits either plug to be removed readily,

each of the illustrated springs 232 being readily movable upwardly into a position in which its lower end is out of engagement with the end face of the plug. To this end each spring has a finger grip 24I (Fig. at its upper end. To

facilitate its removal each plug 220 is provided near its outer end with a peripheral groove 242 into which a screw driver may be inserted. As a tack is driven the plugs 22!] move way from each other to permit the head of the tack and the driving pin to move downwardly between them.

The operation of the illustrated machine is the same in most respects as the operation of the machine illustrated in my copending application, above referred to. The operation of the machine will be briefly described with reference to the butting of storm welts of the type herein illustrated and described. It will be understood that in operating on other types of shoes the welt benders 6B are removed and the crease finders for storm welt work are replaced by other crease finders suited to the type of shoe to be operated upon, the actual cycle of the machine remaining unchanged. The operation is as follows: A shoe held by the operator in inverted position is moved heel foremost into the machine and is located lengthwise thereof by bringing the end stitch of the inseam on each side of the shoe against the cutting edge of the anvil. The shoe is so positioned heightwise thereof that the crease finders locate in the welt crease. The Welt benders are arranged as seen in Fig. 2, when the machine is at rest and they too are located in the welt crease as the shoe is brought into position to be operated upon. After the shoe is thus positioned, the machine is set in motion, whereupon the shoe is gripped between the holddown 26 and the last engaging spindle 20. The knives I41 then operate to butt the welt, then the anvils 91 move outwardly away from the shoe bottom. The tack nozzles then move downwardly into a position adjacent to the upper surfaces of the welt ends. The welt benders then operate to work the welt ends inwardly over the shoe bottom, whereupon the tack nozzles again move downwardly and grip the welt ends against the shoe bottom to hold them in the position into which the welt benders have brought them. The crease finders and the welt benders are then withdrawn from the welt crease, whereupon the tacks are driven, completing the operations on the shoe. Preferably, tack drivers are so adjusted that the tacks are driven through the welt tabs, the overlasted margin of the upper, the flange of the counter wings and the insole and are clenched against the inner surface of the insole.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
